Okay, so you dump the data to disk (tar xv <tarball>), and retar it to tape (tar cvf <tar-dir> <tape dev>). But it looks like the data you got off tape is a tarred archive -- so someone probably created the tarball, and cat'd it onto tape -- or I could be wrong. ;) To cat a file to tape, try; cat <tarball> > <tapedevice> ... which you can now do to create the other 2 tapes. > > I got thefile.tar off of the original tape using > > tar -xv ./thefile.tar -C /usr/thedirectorystore > > The tar file is now on the hard drive.
